"""User Model trust-boundary cases for the live agent battery.

The User Model is the authoritative, *user-corrected* record of who the human is.
Its trust contract is narrow and load-bearing:

  * Explicitly-stated personal facts persist via ``patch_user_model`` (and only via
    blessed APIs — never raw file writes).
  * Inferred / uncertain facts are *proposed*, never auto-applied — they sit pending
    until the human accepts them in the "You" pane.
  * Direct writes/deletes to the model store are refused; the durable model must not
    be mutated behind the user's back.

These cases assert those properties end-to-end with **HTTP state verification** (the
real seam), not just trace inspection:

  * ``prime_user_model_snapshot`` records ``last_updated`` + pending proposal ids
    immediately before the case prompt.
  * ``assert_um_model_changed`` / ``assert_um_model_unchanged`` diff ``last_updated``.
  * ``assert_um_proposal_created`` confirms a reviewable proposal resulted — a new
    pending proposal, or an equivalent already pending (dedupe) so the assertion is
    deterministic regardless of the live proposal pool.

The runner rejects any proposal it created during a case (cleanup) so the live "You"
pane is not polluted. The low-level guard branches (overwrite / append / delete across
model.json, proposals/, checkpoints/, audit.jsonl) are covered exhaustively and
deterministically by ``tests/test_user_model_direct_write_guard.py`` — this file only
carries the behaviors that need a real foreground agent turn.
